插件中的参数说明:
Parametersmenu_idThe id of the menu as defined in your markup. You can bind one or more elements to a menu. Eg $("table td").contextMenu("myMenu") will bind the menu with id "myMenu" to all table cells. Note: This behaviour has changed from r1 where you needed a "#" before the id settingsContextMenu takes an optional settings object that lets you style your menu and bind click handlers to each option. ContextMenu supports the following properties in the settings object: bindings An object containing "id":function pairs. The supplied function is the action to be performed when the associated item is clicked. The element that triggered the current menu is passed to this handler as the first parameter. Note: This behaviour has changed from r1 where you needed a "#" before the id menuStyle An object containing styleName:value pairs for styling the containing <ul> menu. itemStyle An object containing styleName:value pairs for styling the <li> elements. itemHoverStyle An object containing styleName:value pairs for styling the hover behaviour of <li> elements. shadow Boolean: display a basic drop shadow on the menu. Defaults to true eventPosX Allows you to define which click event is used to determine where to place the menu. There are possibly times (particularly in IE6) where you will need to set this to "clientX". Defaults to: ‘pageX‘ eventPosY Allows you to define which click event is used to determine where to place the menu. There are possibly times (particularly in IE6) where you will need to set this to "clientY". Defaults to: ‘pageY‘ onContextMenu(event) A custom event function which runs before the context menu is displayed. If the function returns false the menu is not displayed. This allows you to attach the context menu to a large block element (or the entire document) and then filter on right click whether or not the context menu should be shown. onShowMenu(event, menu) A custom event function which runs before the menu is displayed. It is passed a reference to the menu element and allows you to manipulate the output before the menu is shown. This allows you to hide/show options or anything else you can think of before showing the context menu to the user. This function must return the menu.
通过此插件可以在不同的html元素内建立contextmenu,并且可以自定义样式.
